This product is very suitable for DIY simple mono amplifiers, with built-in boost circuits, and is very
suitable for upgrading or producing battery powered outdoor speakers, telescopic speakers, and
mobile speakers.
After TWS interconnection, two independent speakers instantly become left and right channel stereo
speakers, achieving true wireless connection.

Introduction to box matching function and operation
1.Turn on two power amplifiers of the same model.
2.Select a power amplifier at will, and press the total volume knob with key function inwards three times. At this time,
the blue TWS indicator flashes, and the other power amplifieris automatically paired with it as a stereo combination.
(if the pairing is not successful within 15 seconds, the pairing mode will be canceled automatically. You can try again
by pressing the key three times.)
3.If the pairing is successful, the selected one will be assigned to the left channel, and the blue indicator will always
be on. The other one is the right channel, and the blue indicator will flash slowly.
4.The next time you start the machine, you will automatically find the right box. If you want to cancel the box matching
mode, you only need to select a power amplifier and press the button three times.
